This would have to come from the firmware in the drone looking up what the no-fly zones were. GPS is transmit-only location, it can't write no-fly zone data to a particular drone.

The drone would look it up through a connected cell phone using a web service like this:

https://tfr.faa.gov/tfr_map_ims/html/

I think (hope) it would be a hard sell to send different data from faa.gov to DJI drone lookups versus other brands, but on the other hand this complete brand ban is apparently politically possible.
